Abstract: A fibrous insulation blanket is pre-cut for custom fitting the insulation blanket into structural framework building cavities of different widths. The width of the blanket is substantially equal to the width of a standard cavity to be insulated by the blanket and the blanket has one or more longitudinally extending cuts in a first major surface of the blanket. The cut(s) have a depth greater than one half of the thickness of the blanket and less than the thickness of the blanket whereby the blanket can be handled as a unit for insulating a cavity having a standard cavity width or easily torn apart at a cut by hand for insulating a cavity having less than a standard cavity width. The second major surface of the blanket may have a facing bonded thereto with one or more perforated lines in the facing aligned with the cut(s) to facilitate tearing apart the blanket by hand if required. Preferably, the perforations of the perforated line(s) are closed by the bonding agent bonding the facing to the blanket so that the facing functions as a vapor barrier in spite of the perforations.

Abstract: A pair of grinding wheel carriages, each carrying its own grinding wheel, ar e both carried by a grinding machine to one side of a work carriage and workpiece when carried thereby. The workpiece is, in thi s instance, a camshaft with multiple pairs of similar cams disposed along the axis of the workpiece. The operation control and disposition of the grinding wheels provides for use of either grinding wheel to grind cam pairs or both grinding wheels to simultaneously grind a pair of cam pairs. The method involves first grinding a first cam pair of spaced but in phase cams with one of the grinding wheels; thereafter utilizing both grinding wheels simultaneously to grind two pairs of spaced cam pairs and repeating this step depending upon the number of cam pairs, lastly the final pair of cam pairs is ground utilizing the other grinding wheel. Workspeed for the camshaft is varied depending upon the cam region being ground and to accommodate grinding two cam pairs where the phase angle of one cam pair differs from th e phase angle of the other cam pair.

Inventor: TARNANEN TEEMU
IPC: H04W8/18
Filed: 1998-09-15
Granted: 2008-07-22
Abstract: A digital mobile communication system is provided with a facility by means o f which it can establish a connection to the Internet network (12) via an Internet access point (14, 15). IAP settings needed for establishing a connection are stored in a mobile station (MS). When a mobile station (MS) roams, the closest point may, however, change, and IAP settings should be updated in the mobile station (MS). The invention comprises dividing the mobile communication system into IAP areas, which are given preferred IAPs. An IAP area may be e.g. a mobile communication network (11, 17). Mobile communication networks broadcast system information on the basis of which a mobile station may detect that the IAP area has changed and start a procedur e for updating IAP settings. Updating may comprise retrieval of IAP settings from a special server (13) in the network maintained by an Internet service provider. Retrieval can be done e.g. via a short message service center (10) . In one embodiment the mobile communication network broadcasts messages givin g recommended IAP settings to mobile stations.

Abstract: It is described a testing system of the receivers of a lose transceiver station for cellular telephone systems, for instance GSM 900 MHz, or DCS 1800 MHz, or TACS, etc., equipped with intelligent stray antenna having N sensors. The system consists of a radiofrequency scenario simulation equipment (SIM_RF), governed by a control processor (CONTR_PC), both connected to the bus of an Ethernet network, to which the device under testing (DUT) is also connected. The simulation equipment generates on N outputs (out1, out2..., outN) a complex signal consisting of N identical radiofrequency signals (RF1, RP2,.., RFN) differing among them for a phase progessive value. These signals are withdrawn by a same number of coaxial cables and conveyed towards the N antenna input connectors (in1, in2,..., inN) of the radiofrequency signals of the receiver to be tested. The N test signa ls are obtained through local generation of as many groups of N digital isofrequential carriers as are required to simulate the directions o f a useful signal with an arbitrary number of echoes of the same, and the directions of an arbitrary number of isofrequential interferent carriers, and not, with their relevant echoes. The N carriers of each group are then modulated with appropriate modulation and digitally multiplie d by a same number of relevant beamforming coefficients producing, within each group, an ordering according to gradually increasing phase values.

Title: Methods for exogenous, internal controls during nucleic acid amplification
Inventor: AOYAGI KAZUKO
IPC: G01N33/53
Filed: 1999-03-27
Granted: 2006-11-14
Abstract: Reporter-quencher probe assays of nucleic acid amplification, such as PC R, are rendered more meaningful by the addition of internal control reagents. An internal control polynucleotide is amplified with internal control prime rs and the product is measured by correlation with increased fluorescence by polymerase mediated-exonuclease cleavage or hybridization of the internal control probe. Probes specific for target and internal control polynucleotides are labelled with spectrally resolvable reporters, allowing for concurrent detection and measurement of target and control amplification. A kit of all PCR reagents can be dispensed into reaction chambers in a high-throughput system for rapid and accurate nucleic acid amplification assay, with real-time or end-point measurements. Fluorescent signals correlated to target and internal control levels ar e spectrally resolvable and measured concurrently. A non-extending oligonucleotide or nucleic analog "block", complementary to the internal control polynucleotide, is added to the amplification mixture to preclude amplification of the internal control polynucleotide and function as an internal negative control. The amplification control reagents, kits, and methods of the present invention provide positive and negative control tests occurring within, and measurable within, the reaction chamber.

Title: Rechargeable battery electrode testing device
Inventor: MARTINEAU DANIEL
IPC: G01R31/36
Filed: 2000-12-21
Granted: 2003-09-09
Abstract: A testing device which measures minute changes in battery electrode thickness due to repeated charge/discharge cycles. The testing device uses a moving wall to detect changes in electrode dimensions, typically thickness. The moving wall is adjacent a surface of the electrode, and is connected a sensor that measures wall displacement induced by electrode dimensional changes. Also included in the testing device is a thermocouple that senses the temperature of the device, allowing the data sampling and processing means to correct for thermal expansion/contraction during operation. The testing device can be used during the battery cycling as it does not interfere with the charge/ discharge/recharge process. The testing device can be used to measure either a single electrode, or a plurality of electrodes assembled into an electrode stack and incorporated either into a test cell or into a working battery.

Title: Water-resistant cable
Inventor: COLOMBO GIANFRANCO
IPC: H01B7/28
Filed: 1999-10-06
Granted: 2009-12-15
Abstract: The present invention relates to a cable, in particular an optical fibre cable, which is resistant to the radial permeation and to the longitudinal propagation of water. This cable comprises a water-soluble polymer material, characterized in that the said material is a water-swellable and water-soluble material. In particular, this cable is characterized in that, following the ingress of water into this cable, the propagation of water is impeded on account of the combined effect of the swelling of the water-soluble material and the formation of an aqueous solution of the said material which has a predetermined viscosity, so as to impede the passage of the residual water. Preferably, the water-soluble material is chosen from polyacrylamide, modifi ed polyvinyl alcohol, vinyl alcohol/vinyl acetate copolymers, polyvinylpyrrolidone, and mixtures thereof, the material preferably being a vinyl alcohol/vinyl acetate copolymer. The material can advantageously be extruded to form tubular elements for containing optical fibres, for example two-layer tubular elements in which the inner layer is made of water-soluble material and the outer layer is made of a conventional polymer such as PE, PP or PBT.
